What else can I help you with?
What would happen if you reacted copper with dilute hydrochloric acid?
Probably nothing: Hydrogen is higher than copper in the electromotive series, so that copper can not displace hydrogen from its compounds,
Why does copper not liberate hydrogen on reacting with dilute sulphuric acid?
it is because hydrogen gas usually liberates when an acid reacts with metal
Why lead is not used for the preparation of hydrogen from dilute HCL or dilute sulphuric?
Lead is not reactive enough to displace hydrogen from dilute HCl or dilute sulfuric acid. The reduction potential of lead is lower than that of hydrogen, so it cannot effectively displace hydrogen in these reactions. Other metals like zinc or aluminum are used instead due to their higher reactivity and ability to displace hydrogen.
Why does copper not evolve hydrogen on reacting with dilute sulphuric acid?
Copper does not evolve hydrogen gas when reacting with dilute sulfuric acid because copper is below hydrogen in the reactivity series. This means that copper is not reactive enough to displace hydrogen from sulfuric acid to form hydrogen gas. Instead, copper reacts with sulfuric acid to form copper(II) sulfate and water.
Why Cu does not liberate H2 gas from dilH2So4?
Copper (Cu) is below hydrogen (H) in the activity series of metals, which means it is less reactive than hydrogen. As a result, when copper is placed in dilute sulfuric acid (H2SO4), it is unable to displace hydrogen from the acid to liberate H2 gas. Only metals above hydrogen in the activity series can displace hydrogen from acids to form hydrogen gas.
What would happen if you reacted copper with dilute hydrochloric acid?

What metal cannot displace hydrogen from dilute acid?
Gold is a metal that cannot displace hydrogen from dilute acid due to its low reactivity.

Why does zinc reacts with DI sulfuric acid to give hydrogen gas but not copper?
If you look at reactivity series, you will find zinc to be more reactive than hydrogen while copper being less reactive than it. Therefore zinc is able to displace hydrogen from sulphuric acid while copper is not. The reaction with zinc is:- Zn + H2SO4 -------> ZnSO4 +H2 The reaction with copper is Cu + H2SO4 ---------> No reaction
What is the reaction between copper and sulfuric acid?
No, there is no reaction between copper & H2SO4 because according to reactivity series of metal hydrogen is more reactive than copper. Hence copper does not displace hydrogen from sulphuric acid..
How does copper reacts with acid when copper is below hydrogen in reactivity series?
Cu does not reacts with dilute sulphuric acid but concentrated sulphuric acid reacts with copper inpresence of oxygen and heat here last two factors are responsible for the reaction of copper.
Which 2 metals can displace hydrogen from dilute nitric acid?
magnesium and manganese Mg(s) + 2 HNO3(aq) → Mg(NO3)2(aq) + H2(g)
Why does Fe reacts with dil. H2SO4 to give hydrogen gas but copper does not?
Becayse Iron (Fe) is higher than hydrogen (H) in the chemical reactivity series so it displaces it forming hydrogen gas and Iron sulphate. But Copper (Cu) is lower than hydrogen in the chemical reactivity series so it cannot dispalce hydrogen thus not liberating hydrogen gas
Why Silver Does Not Displace Hydrogen Iron Dilute Acid Solution?
Silver is less reactive than hydrogen and iron in dilute acid solution, so it does not displace them. Silver does not easily donate electrons to form silver ions in acidic conditions, whereas both hydrogen and iron are more reactive and readily undergo redox reactions in the presence of acid. This difference in reactivity means that silver cannot displace hydrogen or iron in dilute acid solution.
